Is cross-band repeat legal?
There is a lot of discussion, but no real consensus that the cross-band repeat function is totally legal according to FCC rules. Most manufacturers have implemented the function in a way that causes unidentified transmissions, Here’s the scenario: When you transmit, you identify your transmission with your callsign.
What is cross-band used for?
Crossband (cross-band, cross band) operation is a method of telecommunication in which a radio station receives signals on one frequency and simultaneously transmits on another for the purpose of full duplex communication or signal relay.
What does repeater capable mean?
Repeaters listen for communications on one frequency and then immediately re-broadcast the transmission on a different frequency, usually at a significantly higher power. For a radio to be repeater capable, it must support having different transmit and receive frequencies for the same channel.
What is band repeater?
A cross-band repeater (also sometimes called a replexer), is a repeater that retransmits a specific mode on a frequency in one band to a specific mode on a frequency in a different band. This technique allows for a smaller and less complex repeater system.
How does a repeater duplexer work?
A duplexer is an electronic device that allows bi-directional (duplex) communication over a single path. In radar and radio communications systems, it isolates the receiver from the transmitter while permitting them to share a common antenna. Most radio repeater systems include a duplexer.
How does a crossband repeating repeater work?
Crossband Repeating Crossband Repeating is a process where a Ham transmits one signal on one band (typically UHF), and it is received by another radio with a better antenna/power installation and re-transmitted (typically on VHF) to another radio system, or a repeater.
Can You remote control a Kenwood crossband repeater?
Some crossband mobiles, such as the Alinco 610, or the “cool blue” Kenwood support limited remote control of the radios. This is handy for remotely shutting off your crossband repeater with your HT. Be aware though, that the commands should not be transmitted through the “live” side of your station, as those tones will also be sent to the repeater.
How does a repeater work on a ham?
Crossband Repeating is a process where a Ham transmits one signal on one band (typically UHF), and it is received by another radio with a better antenna/power installation and re-transmitted (typically on VHF) to another radio system, or a repeater.
How does a cross band transceiver identify a transmitter?
The incoming UHF transmission is identified, and the outgoing vhf transmission is identified, since you are the control operator of your handheld radio and of the cross-band transceiver. On the other side of the transmission, the repeater identifies its own transmissions.
